Opacity fade out appears to end abruptly with onComplete callback

[dgmldr]

Hello,

 

I've discovered a problem when using an opacity animation to 0 along with an onComplete callback that removes the tweened element from the DOM. What essentially I'm experiencing is that the element fades a little bit and then suddenly disappears. Almost as if the onComplete fires before the element reaches 0 opacity.  Click either of the top left buttons to demo.

 

I've found a workaround to adds a timeout to the onComplete callback, delaying the removal of the tweened element by a multiple of the animation duration. Click either of the bottom left buttons to demo. Although the fade-out is smooth and looks right, the hack solution is not desirable. What can be possibly causing the element to "pop" off the page instead of appearing to fade all the way to 0 before onComplete fires

 

Thanks,

DouG

Hi @dgmldr,

 

Please have a look to your CSS

 

.slds-notification {
    position: relative;
    width: 20rem;
    border: 1px solid #ecebea;
    border-radius: .25rem;
    box-shadow: 0 2px 3px 0 rgba(0,0,0,.2);
    transition-duration: .4s;
    transition-timing-function: ease-in-out;
    transition-property: margin,max-height,opacity,top;
  

  
  

 

If you try ...

 

.slds-notification {
    position: relative;
    width: 20rem;
    border: 1px solid #ecebea;
    border-radius: .25rem;
    box-shadow: 0 2px 3px 0 rgba(0,0,0,.2);
    /* transition-duration: .4s; */
    /* transition-timing-function: ease-in-out; */
    /* transition-property: margin,max-height,opacity,top; */
}

 

 you will have a clear responsibility for the job - done by GreenSock.

 

Kind regards

Thank you @mikel! 

I still need the other CSS property transitions, so I pulled just the opacity transition and it works great!

 

.slds-notification {
    position: relative;
    width: 20rem;
    border: 1px solid #ecebea;
    border-radius: .25rem;
    box-shadow: 0 2px 3px 0 rgba(0,0,0,.2);
    transition-duration: .4s;
    transition-timing-function: ease-in-out;
    /* transition-property: margin,max-height,opacity,top; */
    transition-property: margin,max-height,top;
}

 

Greatly appreciated
